(ci. :as-94) 8 Claims.

This invention relates to an adjustable screen ventilator for windows.

An object of the invention is to provide a ventilator device which willtend to air condition rooms in a home, the air entering the room onlythrough the opening in the device.

A further object is to provide a device, or ventilator, as aforesaid,which is adjustable to flt various size Windows and which can besubstantially sealed inthe window. Another object is to provide aventilator as aforesaid having means for filteringthe entering air. l

A further object is to provide a ventilator as aforesaid having improvedconnections between the main part and the adjustable wings.

` Still further, the present invention proposes the prvision ofventilator which is entirely sealed within the window opening, and whichfunctions to admit a controlled `quantity of air through a specificallyprovided opening in the center of the main section.`

Another object of the present invention is to construct a ventilatorwhich may be effectively used under all types of weather conditions andwhich may be used to force air into the room for ventilation purposes,or which may be reversed in its action to discharge stale air from theroom.

A still further object of the present invention is to provide adevicehaving a motor operated fan for moving the air, which has `all ofits operating parts-enclosed with a suitable housing so as to protectthe same against the ruinous` effects of inclement Weather.

A further object of the present invention proposes an inlet opening tothe motor housing provided on three sides with a suitable track systemthe ventilator.

for receiving a filter designed vto remove all dust l Fig. 8 is a rearview of the motor housing looking in the direction of the line 8 8 onFig.. 6.

Fig. 9 is an enlarged section on the lins 9 9 of Fig. l. i

Fig. 10 is an enlarged detail of a portion of Fig. 1 through whichsection line 9 9 is taken. Fig. 11 is a View, similar to Fig. l0, ofthat portion, with the hole therein fully exposed. It is the purpose ofthe present invention to provide a ventilator which will air conditionrooms in the home of a human being. The air will enter the room desiredonly through the opening in the ventilator, and this air is suitablyfiltered before it comes in contact with the fa'n" of the ventilator sothat it is in purer form than if it had been breathed directly from theatmos-4 phere. The ventilator is adjustable to fit in any of a series ofsizes of windows and can be completely edged with foam rubber strips toassure a substantially air-tight nt in the window.

Since the ventilator is tightly held in thewindow opening and since itis completely edged with foam rubber stripping, it will provide aclosure which is air tight except for air entrance for air conditioningthrough the authorized port of the Ventilator. The ventilator can beused to provide ingress of cool fresh air from the outside into theroom, or it can be reversed to provide egress of air from the rcom tothe outside for clearing the room of stale air.

The ventilator includes a box-like compartment for the fan and motor,the compartment being `provided with a filter so that the air enteringthe room can be cleansed. The filter is removable so that if theventilator is reversed, the filter Will not become contaminated by theremoval of dirty air fromthe room. i

The part of the ventilator which is normally l displayed to the eye ofthe occupants of the room ence will be hadto the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention fare'more' particularly setforth.

In the accompanying drawings forming a materialpart of this disclosure:

Fig. 2 is a plan of the ventilator of Fig. 1.

Fig. 3 `is a plan of the main part of the ventilator ofFig. l, the sideWings being eliminated.

Fig. 41s an enlarged vertical section taken on the line 4 5 of Fig. l.

Fig. 5 is an enlarged section on the line 5 5 of Fig. 1. l

is neat and attractive in appearance. The ventilator has a main femalepart and lateral adjustable male wings. The top and bottom arssymmetrical, the only difference being that there is an opening in thefront face near the bottom for an electric cord.

The ventilator I 0, constructed in accordance with the presentinvention, can be utilized with The of the window frame` l2 and thebottom sash I 3 is forced down on top of the ventilator. ventilator inany of its adjusted sizes is rectangm lar and when it is placed in thewindow, it is first l The ventilator` has a main female part `l 5. ThisThe l part is formed partly of a long rectangular piece of sheet metalprovided at its center with a 01rcular hole i6 forming part of the airduct. It is bent at its top and b-ottom, at right angles, to

form a top wall Il and a bottom wall i8, the remainder of the sheetforming a front wall I9, in which the hole I6 is located. A member isfastened, as by screws 2lia or the like, to each of the top and bottomwalls. Each member consists of portion 2i) superposed on wall lll or It,as the case may be, a rear iiange 2l, a front flange 22 and superposedon wall i9, and a channel 23 integral with front flange 22. The twochannels 23 are oppositely disposed, the top one opening upwardly andthe bottom one opening downwardly. At its ends, each flange 2l is cut toform tabs 2l=L which are bent under and fastened to the'bottom of wallIl or i3'. Each wall 20 has a slot 24 extending from each of itsopposite ends toward, but not to, the middle of the Ventilator, see Fig.3.

The ventilator has two male wings 25. The wings are identical and one isshown in Fig. '7. It has a front wall 2t and top, bottom and outer endwalls 2l, 28 and 2S respectively. The front wall has a vertical slit 3@and is cut through its edge opposite wall 29 from slit Se to provide topand bottom tongues 3l. In its assemblage with the female portion, thewalls 2'! and 28 fit into the top and bottom slots 2li respectively andthe tongues 3| slide in the channels 23. Thus, the overall length of theventilator may be adjusted by sliding the male wings 25 relative to thefemale part l5. The male wings are designed for easy adjustment of theventilator to different sized windows.

A box-like compartment 3?. is secured to the inner face of the main.female part i over the hole i6, this compartment being rectangular incross section and having a flange 33 attached to the wall i9. One end ofthe compartment is formed on three sides with a track system 311 forreceiving a lter 35. The lter 35 slides througha slot 36 formed in oneof the side walls of the compartment, and the tracks extend from thecompartment 32 at Ithe top and bottom of the slot 36 to facilitateinsertion and removal of the ilter 35, which is provided with a knob 35aby which it may be manually gripped. A fan 3l, with an electric motor38, is supported in the compartment, the electric cord 3S of the motorpassing through a hole in the bottom of the compartment. The hole i6, inthe wall i9, is covered by a wire screen 40 for safety precautions.

The fan is directed to blow cold or fresh air from the atmosphere intothe room, the air passing through the iilter to the ian and being forcedthrough the screen il@ into the room. If it is desired to blow or drawthe air out of the room, the entire ventilator can be reversed, placingthe compartment in the room and removing the lter, or the motor can bereversed, if it is a reversible motor, the filter rst being removed. Thefilter is made of several layers of iine wire screen` The foam rubbersubstantially seals the venti'- later except for the hole l5, wherebyall the air entering the room must be ltered. The electric cord 39 mustenter the room for connection with the usual wall socket, not shown, anda rectangular hole 4l is provided in the wall lil' for this purpose, thehole 4l being just large enough for a small male plug t2' to passthrough. Since the wire 39 will occupy the hole il it is desired toclose this hole as much as possible to lmaintain the air tight conditionof the ventilator. To accomplish this, a small frame 43 is fastened tothe innerface of wall I9 about the hole 4l and two small sliding doors44 are positioned in the frame, each door 44 having a semicircularopening 45. These doors are moved apart (Fig. 11) to permit the passingof the plug 42 through the hole 4l, and are moved together (Fig. l0) toleave a hole only the size of the cord 39 so that cord 39 seals the holeand no space for leakage is left. This is important for if theVentilator is reversed, the plug must be returned through the hole 4| asthe compartment will then be in the room, and if the plug were notreturned, it would be hanging out of the window.

It is to be understood that theopeningsmay be in the form of a deepslotandtheemembers-.M may be of C-shape; One of these members. may beleft permanently in position while the other sliding door 44 may bemoved to any adjusted position to accommodate the electric wire andplug.

While I have illustratedandV described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modications coming within the scope of the invention asdefined in the appended claims.
